H. R. CULLMER DOORLOCK AND FRAMING Filed Oct. 3, 1929 2 Sheets-Sheet 2 Patented Feb, 6, 1934 UNITED STATES PATENT OFFICE 1,945,734 DOORLOCK AND FRAMING Harry R. CullmenHollis, N. Y. Application October 3,- 1929. Serial No. 396,964 '1 Claims. (01. 187-31) My invention relates to improvements in door operating and control mechanism especially adapted for use in the construction of elevator hatchways, and more particularly has reference to and is illustrated in the accompanying draw-.

ings in its application to the construction of ele vator door framing and doors and the operating mechanism in connection therewith.

Referring to said drawings, Fig. 1 illustrates in plan view parts being broken away and parts in cross-section, part of the door and framing and elevator hatchway showing an embodiment of my invention. Fig. 2 'is a vertical section, parts broken away, illustrating one form of 011'- cuit control mechanism. Fig. 3 is another vertical sectional view similar to Fig. 2 except that it applies for a sliding or rolling door as distinguished from a. hinged or swing door. Fig. 4 is a perspective detail illustrating contact mechanism for a swinging door, and Fig. 5 a similar view for such device for a rolling or sliding door. Fig. 6 is a cross-section on the line 6-6 of Fig; 2. Fig. '7 is an enlarged perspective detail, parts broken away, showing the interior mechanism for hinged door control, and Fig. 8 is an enlarged detail of a shoe for operating in co-operation with the mechanism shown in Fig. '7.

Referring now more particularly to Figs. '7 and 8, it should be understood that the shoe illustrated in Fig. 8 is carried by the car and is pivotally mounted on the support 9 as indicated at 10, 11. The bellcrank members 12, 13 are pivotally connected to the shoe 14 as shown and the bellcrank 13 is preferably pivotally connected at 15 to the chain 16 which in turn is secured to a suitable magnet in circuit with the motor. The leg 1'? of the bellcrank 12 is pivotally connected to the extension spring 18 anchored at 19 as shown, from all of which it will be understood that when the current has been cut off from the motor, the magnet as shown, in circuit therewith, releases the chain 16 thereby allowing the extension spring 18 to withdraw or contract thereby, lifting the leg 1'7 of the bellcrank 12 and throwing theshoe downwardly and outwardly.

When projected outwardly, the shoe 14 is in the path of the pulley or wheel 20 at the right side thereof looking at Fig. 7; This pulley or roller 20 is pivotally mounted at 21 upon the arm 22 which in turn is securedupon the shaft 23 by means of a set screw 24 with suitable bearing adjustment as indicated at 25. This shaft 23 also has formed therewith or secured thereon an arm 26, the upper end of which carries an insulation block 27, and the lower end of which is provided with an arm 27, the latter pivotally engaging the bolt 28 slidably mounted in straps 29 and normally projected outwardly by spring 28 in alignment with the plane of the door when closed, having a bevelled end 30 as shown. Should the door be accidentally left open and the bolt projected, upon closing it the edge of the door striking the bevelled end 30 of the bolt 28 places the mechanism in inoperative position but when the bolt 30 is projected, the door is presumed to be closed and 85 locked thereby, thus leaving the mechanism in an operative position; in other words, the mechanism when inoperative with the door closed keeps the circuit closed as hereinafter described, but when the door is opened with the bolt 28 withdrawn, the mechanism is inoperative and the circuit is open.

This circuit controls the buttons for operating the car both on the cars and on the floors and has included in the circuit the switch 31 provided with contacts 32, 33 having buttons such as, 34 adapted to be bridged by the metallic channel 35 which in turn is loosely mounted upon pins 36, shown to advantage in Fig. 6 and is normally projected by compression spring 37, also shown to advantage in Figs. 6 and 2, thus allowing the channel 35 to properly and flatly contact with the buttons 34, closing the circuit 32, 33 which switch 31 being in series with the button control renders the buttons inoperative when opened, and which switch is always closed when the car is at any point in the shaft other than at the immediate floor intended, the switch being opened at such point by the projection of shoe 14 as explained.

By reference now more particularly to Fig. 1 it will be observed that the door 38 is provided preferably at the top with an 'L-shaped bracket or contact member shown to advantage inFig. 4, one leg 40 of the, bracket being secured to the door as shown in Fig. 1 and the other leg 39 hav ing suitable lugs 41 for retaining the insulated block 42 with the metallic end 43.

Byreference now more particularly to Figs. 2 and 3, and especially the latter, it will be observed that this contact end 43 forces its way 1 between the contact members 44, 45 closing the circuit 46, 47 when the door is closed. It will, therefore, be understood that the door must be closed before the push buttons on the floor or on the car can be operated, the switch 48 being like 0 the switch 31 connected suitably in series with the push button or control circuit. Again, the door must be closed to close the switch 48 and the car must be at the intended floor in order for the switch 31 to be opened and closed and only when 110 both switches are thus in both operative position can the car be operated either from aboard the car or from any floor. What has been said with reference to Fig. 4 as a contact plug for closing switch 46, 47 when the door is hinged applies with equal force to the contact plug shown in Fig. 5 which is adapted for use on the end of a rolling or sliding door, same being suitably secured by screws through the base 40', the contact end 43' spanning and connecting the contacts such as 44, 45.

By reference now more particularly to Fig. 3 it will be observed that instead of operating a slide bolt, such as 28, a hook 49 may be operated, the same being secured upon the shaft 23 so that when said shaft is rotated by virtue of the projection of shoe 14, the hook 49 is lifted upon the center 23, thus releasing a sliding or rolling door as distinguished from a hinge or swinging door, the mechanism otherwise being substantially the same and, in either case, the bracket or arm 22 is preferably weighted as indicated at 50 to normally oppose by gravity the action of the shoe 14, thereby keeping the arm 22 more vertically suspended in the path of the shoe 14 from which path it is diverted as the end of the shoe 14 strikes the same on its upper or downward travel.

With reference now again more particularly to Fig. 7 it will be observed that the wall 51 may be plastered as indicated at 52 and the sheet metal frame may be secured at the end as indicated at 53 passing leftwardly over the edge of the plaster, outwardly as indicated at 54, forming a suitable moulding effect and finally inwardly as indicated at 55, terminating at 56 as shown. A superimposed moulding effect may be secured thereto as indicated at 57 by screw or bolt carrying leftwardly and inwardly, terminating at 58 where the same may be retained by a clip or other suitable means as indicated at 59. A facing 60 may also be provided as shown and a tie-bar 61 may be passed therethrough holding the combination in position as shown. Thus, it will be readily understood, allows for several adjustments for walls of different size and conditions, thus making the door framing adjustable and allowing'the finished plastering to proceed before the same is applied. 62 and 63 indicate brackets suitably secured and providing support for a box-like structure 65 within which mechanism hereinbefore described may be mounted, as shown, and 64 indicates a face-plate removably mounted and provided with a cutaway portion as indicated at 66 for the passage of the hub 67 of the arm 22 when necessary to remove the same from enclosure. 68 indicates the end of the armored conduit through which the wires enter the box 65 for connection with the switch 31, and the same applies to the box connector 69 and flexible conduit '70 shown in Figs. 2 and 3.

Of course, it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
